ABSTRACT:
A process for effecting an annealing treatment of a spheroidal or lamellar graphite cast iron pipe. While the pipe is driven in rotation about the axis of the pipe, it is suspended substantially horizontally as it issues from the centrifugal casting machine and the pipe is partly immersed in a bath of metal at the desired temperature. An installation for carrying out this process comprises an elongate vessel having a horizontal axis and containing a bath of molten metal at the required temperature. A withdrawable device is provided outside the bath for suspending the pipe in a substantially horizontal position and plunging the pipe partly in the bath while driving the pipe in rotation about the axis of the pipe.
